Hello, my first post and a simple question I can't seem to find the answer elsewhere.
So I need to amplify an RF signal, but its power range from +15dBm to -120dBm
The system need to input a 2.5DC 1V p-p signal into the ADC for frequency analysis, but I'm not so sure how to amplify the signal for such a large dynamic range. If I use an Op-Amp chain with a limiting stage at the end, what if the signal is strong and a stage before the limiting amp reaches saturation? I don't think most such systems use all limiting amplifiers, but then how did they do it?
Any ideas?
Thanks.
